If you encounter issues with your NEBULA Capsule Air, refer to the following common problems and solutions:
- No Image/Dim Image:
- Ensure the projector is powered on and fully charged or connected to power.

- No Sound/Low Sound:
- Check the volume level on the projector and any connected external devices.
- Ensure Bluetooth speakers are properly paired and connected.
- If using HDMI, verify the audio output settings on the source device.
- Wi-Fi/Bluetooth Connectivity Issues:
- Restart the projector and your Wi-Fi router/Bluetooth device.
- Ensure the projector is within range of the Wi-Fi network or Bluetooth device.
- Check Wi-Fi password and network settings.
- App/Software Issues:
- Ensure the projector's software is up to date via system settings.
- Clear cache and data for problematic apps in the Android settings.
